IL-6 Regulation of Energy Stores During Recovery From an Acute Exercise Bout (REX-6)

25. oktober 2022 opdateret af: Helga Ellingsgaard

Role of IL-6 in Regulating Energy Stores During Recovery From an Acute Exercise Bout

The aim of the study is to investigate the role of exercise-induced IL-6 in regulating energy stores and energy metabolism during recovery after an acute exercise bout. To achieve this, 30 men will be randomized to infusion placebo or tocilizumab (IL-6 receptor antibody) combined with a 2-hour exercise bout. Stable isotope tracers will be infused to determine substrate kinetics. Indirect calorimetry will be applied to determine substrate oxidation, and muscle biopsies will be taken to determine substrate uptake and storage.

Våben og indgreb

Deltagergruppe / Arm
Intervention / Behandling
Eksperimentel: Tocilizumab
Participants will receive one 30 min intravenous infusion of tocilizumab/Actemra® (Roche). The dose will be 8 mg/kg bodyweight or a maximum of 800mg. Tocilizumab is dissolved in 100 mL 0.9% saline.
Medicin: Tocilizumab/Actemra® (Roche)
The infusion of tocilizumab will antagonize IL-6 signaling for the duration of the study, allowing us to determine the role of IL-6 in regulating energy stores following acute exercise
Placebo komparator: Saline
As placebo, participants will receive one 30 min intravenous infusion of 100 mL 0.9% saline.
Medicin: Saline 9%
The infusion of saline will serve as placebo for tocilizumab, allowing us to determine the role of IL-6 in regulating energy stores following acute exercise
